The worst thing that you can do while between jobs is stagnate. If you give up and stop pushing, learning, and growing it will not only take longer to find a job, but the waiting will be more painful. This is why periods between full-time employments are the perfect times to pick up new skills. This could mean signing up for a class, buying a couple books, or just devoting a couple hours each day to utilizing free online educational resources (of which there are many!). These days the most useful hard skill (by far) is programming. If you know how to code you can be useful at pretty much any company, and can even find ample work as a free-lancer!
